A problem may occur when you are normalizing your data. If you happen to see a blank graph after the normalization has been completed, you may want to do one of the following things.
1) Change the sensitivity in the Reference_Selection.m
At line 65 in the function, you will see "handles.sensitivity=2.25". The number after sensitivity may be different. You usually will want to change the value to a lower number. The lower the sensitivity, the more data that is removed. You can adjust the sensitivity to whatever value that you would like.
2) If that doesn't seem to fix your problem, go to line 161 in Reference_Selection.m
At line 161 you will see the following: "plot(DNA_Pos_data_mat_norm_min)". Go ahead and remove the "DNA_Pos". You should be left with the following: "plot(dat_mat_norm_min)".
3) If there is still an issue, go to line 172 in Reference_Selection.m
At line 172 add "-1" to end of the line. The line should read as follows: "for i=1:size(dat_mat_norm_min,1)-1"
